Hello Rick, hello Bin,
when I run qemu-riscv64_defconfig using
qemu-system-riscv64 -machine virt -m 1G -nographic \ -bios u-boot \ -device virtio-net-device,netdev=net0 \ -netdev user,id=net0,tftp=tftp
a crash occurs in riscv_get_time() when executing readq().
$ qemu-system-riscv64 --version QEMU emulator version 5.0.0 (Debian 1:5.0-13)
Looking at doc/board/emulation/qemu-riscv.rst this should work.
Is there something missing in the documentation?
You can try this ./qemu-system-riscv64 -nographic -machine virt -bios u-boot -device virtio-net-device,netdev=net0 -netdev user,id=net0,tftp=tftp
It can work as below:
U-Boot 2020.10-rc1-00299-g89150a9 (Aug 06 2020 - 19:14:01 +0800)
CPU: rv64imafdcsu Model: riscv-virtio,qemu DRAM: 128 MiB In: uart@10000000 Out: uart@10000000 Err: uart@10000000 Net: eth0: virtio-net#0 Hit any key to stop autoboot: 0 => help
But on Debian Bullseye it fails:
$ git reset --hard origin/master $ make mrproper $ make qemu-riscv64_defconfig $ export CROSS_COMPILE $ export CROSS_COMPILE=riscv64-linux-gnu- $ qemu-system-riscv64 -nographic -machine virt \
-bios u-boot \ -device virtio-net-device,netdev=net0 \ -netdev user,id=net0,tftp=tftp
Just rebuilt a QEMU 5.0.0 on Ubuntu 16.04 and cannot reproduce. Something is wrong with Debian?
